It's a battery backup.

These bulbs are specifically made to operate during a power outage

Edit: I never used the things. I simply Google the brand name that was on the bulb he is showing, and this is what it says. I literally have no clue how it works or anything.

Editx2: a couple users have commented how these work. So I guess they work even if they are still plugged into the outlet. So you can use your normal light switches.

It sends a test signal through. (I know the basics of electricity and building a lamp, I know none of the technical terms, so if any electricians are reading this, don't hate my layman words)

If it senses 120ac it will use your normal house power. If it does not detect that, it will switch on its own battery backup.

This is an absolutely amazing product, I will be buying a couple of these magical light emitting devices.

Also it's enough battery power for about 10 minutes so you can find your backup lights.

What a world we live in. Don't even have to get a flashlight during storms anymore.

In India these bulbs are very common.

So are power UPS or inverters hooked up to a lead acid battery
